JOHN OESTERLING, OF WHEELING, WEST VIRGINIA.

Specification forming part of Letters Pa SPECIFICATION.

To all whom it may concern:

Be it known that I, JOHN OESTERLING, of Wheeling, in the county of Ohio and State of West Virginia, have invented a new and useful Improvement in Cooling-Stand for Glass- Ware; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had by letters to the accompanying drawing making a part of this specification, in which Figure 1 represents in perspective a stand for cooling glass-ware, with my improved arrangement of blow-pipes affixed thereto; and Fig. 2 illustrates a modified construction of the blow-pipes.

In articles of pressed or blown glass-ware of unequal thickness in different parts, some trouble is experienced in cooling, from the fact that the thinner parts will cool first. In goblets, for example, as ordinarily made, the bowl will chill almost or quite as soon as the presser can take it out of the mold; but the leg or stem will remain in a semi-fluid or such plastic condition that, when placed on a stand to cool, it is liable to bend one way or the other. To overcome this difficulty, a jet of air has been applied by hand-bellows and other means; but in this way onlyone side was cooled at a time, with the result, in many cases, of unequal chilling, bending and cracking.

Previous to my invention, I am not aware of any apparatus which would secure the speedy and uniform chilling of such parts of such articles of glass-ware under the conditions above stated.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and mode of operation.

A cooling-stand of any suitable construction is represented at B. To such a stand I affix a system of pipes, substantially as shown. From any suitable blowing apparatus or compressedair reservoir a r movable hose-pipe, having a suitable nozzle 0 coupling, leads to the pipe a, the end of which is fitted for coupling in like manner. This pipe extends down through or under the stand-plate B, (as indicated by dottent No. 124,378, dated March 5, 1872.

ted lines,) where it branches into two or three or more arms, which extend out in opposite directions, and there pass up through or outside the stand-plate B, as indicated at b, and at such distance apart as to leave room between them for placing therein the article of glass-ware to be cooled. These pipes I) extend up to the height, or about the height, at which it is desired to apply the air for cooling; and on the upper end of each I afl'ix an open elbowjoiut, b, turned inward toward the center, so that a jet of air from each will play on the part of the article to be cooled. In order to regulate the force of the air-jets, a cock, 0, may be introduced at any desired point. These jet-pipes should be two or more in number, and arranged opposite to each other, so as to play on two or more of the opposite sides of the glass, and thereby secure uniformity in cooling, as well as speed. An arrangement of pipes of the class indicated is attached permanentlyto each cooling-stand, so that, in changing stands, as is often necessary, it is only needful to remove the hose nozzle, coupling, or union from the pipe at of one stand to the corresponding pipe of another. Instead of the system of pipes described, I sometimes employ an annular pipe, m, Fig. 2, having a series of ports, a, in any desired number, arran ged at suitable height above the stand and relatively to each other, so as to direct jets of air from opposite directions onto the glass article to be cooled. This annular pipe m may be furnished with a supply-pipe, m, as before. The pipem, instead of being annular, may be made rectangular or of other suitable shape.

What I claim as my invention, and desire to secure by Letters Patent, is'

A system of cooling blow-pipes, or a single pipe, m having blo win g ports or apertures, two or more in number, affixed to a glassware-coolin g stand, such ports being arranged opposite to each other and relatively to the article to be operated on substantially as set forth.

In testimony whereof I, the said JOHN OES TERLING, have hereunto set my hand.

JOHN OESTERLING.
